Building Services Solutions Suitable for a Low Emission Urban Areas

Abstract

It is believed that well-performing building envelopes with low thermal losses and low solar heat gains enable simplified building services solutions. The purpose of this report is to summarize the status of promising building services solutions suitable for a low emission building stock in urban areas. The solutions are selected as relevant for use by the ZEN partners, the ZEN pilot areas and for further research in FME ZEN. The conclusion includes recommendations on which technologies are promising, for which building categories they are suitable and where the limitations are for each technology. From the table we can conclude that all the technologies have proven to be promising for office buildings (both new and renovated). In addition to the technologies in the table, responsive lighting equipment, smart energy control, and utilization of surplus heat sources are considered promising for all building categories. Technical installations should utilize low-temperature heating and high-temperature cooling in order to better utilize renewable energy sources and surplus energy, and to reduce heat loss from the systems. Future building services in new and renovated existing buildings should aim for an optimization between energy, power, and indoor environmental performance. A comprehensive approach is needed for assessing energy performance, comfort quality, and economic feasibility of low energy building service
